1615–1625: The original use was to describe insects, apparently as a variant of the earlier bugge (beetle), thought to be an alteration of the Middle English budde, from the Old English -budda (beetle) but etymologists are divided on whether the phrase “bug off” (please leave) is related to the undesired presence of insects or was of a distinct origin.  Bug, bugging & debug are nouns & verbs, bugged is a verb & adjective and buggy is a noun & adjective; the noun plural is bugs.  Although “unbug” makes structural sense (ie remove a bug, as opposed to the sense of “debug”), it doesn’t exist whereas forms such as the adjectives unbugged (not bugged) and unbuggable (not able to be bugged) are regarded as standard.

Nerd humor.

The array of compound forms meaning “someone obsessed with an idea, hobby etc) produced things like “shutterbug” (amateur photographer) & firebug (arsonist) seems first to have emerged in the mid nineteenth century.  The development of this into “a craze or obsession” is thought rapidly to have accelerated in the years just before World War I (1914-1918), again based on the notion of “bitten by the bug” or “caught the bug”, thus the idea of being infected with an unusual enthusiasm for something.  The use to mean a demon, evil spirit, spectre or hobgoblin was first recorded in the mid-fourteenth century and was a clipping of the Middle English bugge (scarecrow, demon, hobgoblin) or uncertain origin although it may have come from the Middle Welsh bwg (ghost; goblin (and linked to the Welsh bwgwl (threat (and earlier “fear”) and the Middle Irish bocanách (supernatural being).  There’s also speculation it may have come from the scary tales told to children which included the idea of a bugge (beetle) at a gigantic scale.  That would have been a fearsome sight and the idea remains fruitful to this day for artists and film-makers needing something frightening in the horror or SF (science fiction) genre.  The use in this sense is long obsolete although the related forms bugbear and bugaboo survive.  Dating from the 1570s, a bugbear was in folklore a kind of “large goblin”, used to inspire fear in children (both as a literary device & for purposes of parental control) and for adults it soon came to mean “a source of dread, resentment or irritation; in modern use it's an “ongoing problem”, a recurring obstacle or adversity or one’s pet peeve.  The obsolete form bugg dates from circa 1620s and was a reference to the troublesome bedbug, the construct a conflation of the middle English bugge (scarecrow, hobgoblin) and the Middle English budde (beetle).  The colloquial sense of “a microbe or germ” dates from 1919, the emergence linked to the misleadingly-named “Spanish flu” pandemic.

Bugs: A ground beetle (left), a first generation der Käfer (the Volkswagen Beetle, 1938-2003) (centre) and an "New Beetle" (1997-2011).  Despite the appearance, the "New Beetle" was of front engine & front-wheel-drive configuration, essentially a re-bodied Volkswagen Golf.  The new car was sold purely as a retro, the price paid for the style, certain packaging inefficiencies.  Few have ever questioned why the original VW Beetle picked up the nickname “bug”.

Like the rest of us, even scientists, entomologists and zoologists generally probably say “bug” in general conversation, whether about the insects or the viruses and such which cause disease but in writing academic papers they’ll take care to be more precise.  Because to most of us “bugs” can be any of the small, creepy pests which intrude on our lives (some of which are actually helpful in that quietly and unobtrusively they dispose of the really annoying bugs which bite us), the word is casually and interchangeably applied to bees, ants, bees, millipedes, beetles, spiders and anything else resembling an insect.  That use may be reinforced by the idea of the thing “bugging” us by their very presence.  To the professionals however, insects are those organisms in the classification Insecta, a very large class of animals, the members of which have a three-part body, six legs and (usually) two pairs of wings whereas a bug is a member of the order Hemiptera (which in the taxonomic system is within the Insecta class) and includes cicadas, aphids and stink bugs; to emphasize the point, scientists often speak of those in the order Hemiptera as “true bugs”.  The true bugs are those insects with mouthparts adapted for piercing and sucking, contained usually in a beak-shaped structure, a vision agonizingly familiar to anyone who has suffered the company of bedbugs.  That’s why lice are bugs and cockroaches are not but the latter will continue to be called bugs, often with some preceding expletive.

9 September 1947: The engineer's note (with physical evidence) of electronic computing's "first bug".

In computing, where the term “bug” came to be used to describe “glitches, crashes” and such, it has evolved to apply almost exclusively to software issues and even if events are caused by hardware flaws, unless it’s something obvious (small explosions, flame & smoke etc) most users probably assume a fault in some software layer.  The very first documented bug however was an interaction recorded on 9 September 1947 between the natural world and hardware, an engineer’s examination of an early (large) computer revealing an insect had sacrificially landed on one of the circuits, shorting it out and shutting-down the machine.  As proof, the unfortunate moth was taped to the report.  On a larger scale (zoologically rather than the hardware), the problem of small rodents such as mice entering the internals of printers, there to die from various causes (impact injuries, starvation, heat etc) remains not uncommon, resulting sometimes in mechanical damage, sometimes just the implications of decaying flesh.

Revelle's Bug Bomb, 1970.

The idea of a bug as a “defect, flaw, fault or glitch” in a mechanical or electrical device was first recorded in the late 1800s as engineer’s slang, the assumption being they wished to convey the idea of “a small fault” (and thus easily fixed, as opposed to some fundamental mistake which would necessitate a re-design).  Some sources suggest the origin lies with Thomas Edison (1847-1931) who is reported as describing the consequences of an insect “getting into the works”.  Programmers deploy an array of adjectives to "bug" (major, minor, serious, critical & non-critical etc) although between themselves (and certainly when disparaging of the code of others) the most commonly heard phrase is probably “stupid bug”.  The “debugging” (also as de-bugging) process is something with a wide definition but in general it refers to any action or set of actions taken to remove errors.  The name of the debug.exe (originally debug.com) program included with a number of (almost all 16 & 32-bit) operating systems was a little misleading because in addition to fixing things, it could be used for other purposes and is fondly remembered by those who wrote Q&D (quick & dirty) work-arounds which, written in assembler, ran very fast.  The verb debug was first used in 1945 in the sense of “remove the faults from a machine” and by 1964 it appeared in field service manuals documenting the steps to be taken to “remove a concealed microphone”.  Although the origin of the use of “bug” in computing (probably the now most commonly used context) can be traced to 1947, the term wasn’t widely used beyond universities, industry and government sites before the 1960s when the public first began to interact at scale with the implications (including the bugs) of those institutions using computerized processes.  Software (or any machinery) badly afflicted by bugs can be called “buggy”, a re-purposing of the use of an adjective dating from 1714 meaning “a place infested with bugs”.

Some bugs gained notoriety.  In the late 1990s, it wasn’t uncommon for the press to refer to the potential problems of computer code using a two-numeral syntax for years as the “Y2K bug” which was an indication of how wide was the vista of the common understanding of "bug" and one quite reasonable because that was how the consequences would be understood.  A massive testing & rectification effort was undertaken by the industry (and corporations, induced by legislation and the fear of litigation) and with the coming of 1 January 2000 almost nothing strange happened and that may also have been the case had nothing been done but, on the basis of the precautionary principle, it was the right approach.  Of course switching protocols to use four-numeral years did nothing about the Y10K bug but a (possible) problem 8000 years hence would have been of little interest to politicians or corporate boards.  Actually, Ynnn~K bugs will re-occur (theoretically with decreasing frequency) whenever a digit needs to be added.  The obvious solution is trailing zeros although if one thinks in terms of infinity, it may be that, in the narrow technical sense, such a solution would just create an additional problem although perhaps one of no practical significance.  Because of the way programmers exploit the way computers work, there have since the 1950s been other date (“time” to a computer) related “bugs” and management of these and the minor problems caused has been handled well.  Within the industry the feeling is things like the “Y2038 problem” will, for most of the planet, be similarly uneventful.

The DOSShell, introduced with PC-DOS 4.0; this was as graphical as DOS got.  The text-based DOSShell was bug-free and a reasonable advance over what came before but the power users had already adopted XTree as their preferred file handler.

Bugs can also become quirky industry footnotes.  As late as 1987, IBM had intended to release the update of PC-DOS 3.3 as version 3.4, reflecting the corporation’s roadmap of DOS as something of an evolutionary dead-end, doomed ultimately to end up in washing machine controllers and such while the consumer and corporate market would shift to OS/2, the new operating system which offered pre-emptive multi-tasking and access to bigger storage and memory addressing.  However, at that point, both DOS & OS/2 were being co-developed by IBM & Microsoft and agreement was reached to release a version 4 of DOS.  DOS 4 also included a way of accessing larger storage space (through a work-around with a program called share.exe) and more memory (in a way less elegant than the OS/2 approach but it did work, albeit more slowly), both things of great interest to Microsoft because they would increase the appeal of its upcoming Windows 3.0, a graphical shell which ran on top of DOS; unlike OS/2, Windows was exclusive to Microsoft and so was the revenue stream.  Unfortunately, it transpired the PC-DOS 4.0 memory tricks were “buggy” when used with some non-IBM hardware and the OS gained a bad reputation from which it would never recover.  By the time the code was fixed, Microsoft was ready to release its own version as MS-DOS 4.0 but, noting all the bad publicity, after some cosmetic revisions, the mainstream release was MS-DOS 4.01.  In the code of the earlier, bug-afflicted bits, there seems no substantive difference between MS-DOS 4.01 the few extant copies of MS-DOS 4.0.

Herbie, the love bug

Lindsay Lohan (left) among the bugs (centre) on the red carpet for the Los Angeles premiere of Herbie Fully Loaded (a 2005 remake of The Love Bug (1968)), El Capitan Theater, Hollywood, Los Angeles, 19 June 19, 2005.  The Beetle (right) was one of the many replica “Herbies” in attendance and, on the day, Ms Lohan (using the celebrity-endorsed black Sharpie) autographed the glove-box lid, removed for the purpose. 

In idiomatic and other uses, bug has a long history.  By the early twentieth century “bugs” meant “mad; crazy" and by then “bug juice” had been in use for some thirty years, meaning both “propensity of the use of alcoholic drink to induce bad behaviour” and “bad whiskey” (in the sense of a product being of such dubious quality it was effectively a poison).  A slang dictionary from 1811 listed “bug-hunter” as “an upholsterer”, an allusion to the fondness bugs and other small creatures show for sheltering in the dark, concealed parts of furniture.  As early as the 1560s, a “bug-word” was a word or phrase which “irritated or vexed”.  The idea of “bug-eyed” was in use by the early 1870s and that’s thought either to be a humorous mispronunciation of bulge or (as is thought more likely) an allusion to the prominent, protruding eyes of creatures like frogs, the idea being they sat on the body like “a pair of bugs”.  The look became so common in the movies featuring aliens from space that by the early 1950s the acronym BEM (bug-eyed monster) had become part of industry slang.  The correct term for the medical condition of "bulging eyes" is exophthalmos.

To “bug someone” in the sense of “to annoy or irritate” seems not to have been recorded until 1949 and while some suggest the origin of that was in swing music slang, it remains obscure.  The now rare use of “bug off” to mean “to scram, to skedaddle” is documented since 1956 and is of uncertain origin but may be linked to the Korean War (1950-1953) era US Army slang meaning “stage a precipitous retreat”, first used during a military reversal.  The ultimate source was likely the UK, Australian & New Zealand slang “bugger off” (please leave).  The “doodle-bug” was first described in 1865 and was Southern US dialect for a type of beetle.  In 1944, the popular slang for the German Vergeltungswaffen eins (the V-1 (reprisal weapon 1) which was the first cruise missile) was “flying bomb” or “buzz bomb”) but the Royal Air Force (RAF) pilots preferred “doodle-bug”.

The ultimate door-stop for aircraft hangers: Bond Bug 700.

The popularity of three wheeler cars in the UK during the post-war years was a product of cost breakdown.  They were taxed at a much lower rate than conventional four-wheel vehicles, were small and thus economical and could be operated by anyone with only a motorcycle licence.  Most were genuine (if not generous) four-seaters and thus an attractive alternative for families and, being purely utilitarian, there were few attempts to introduce elements of style.  The Bond Bug (1970-1974) was an exception in that it was designed to appeal to the youth market with a sporty-looking two-seater using the then popular “wedge-styling” and in its most powerful form it could touch 80 mph (130 km/h), faster than any other three wheeler available.  The bug was designed by Vienna-born British designer Tom Karen (1926–2022) who intended it as a “Ferrari for 16-year-olds” which may hint he knew more about cars than young males but in the 1970s such comparisons often were made, a tester in one magazine describing the diminutive Fiat 127 (1971-1983) as “the 0.9 litre Ferrari” which was journalistic licence writ large but people knew what he meant.

An infestation of Bugs.

However, the UK in 1973 introduced VAT (value-added tax, a consumption tax) and this removed many of the financial advantages three-wheelers offered (it also doomed much of the “kit-car” business in which customers could buy the parts and assemble them with their own labor).  In an era of rising prosperity, the appeal of the compromise waned and coupled with some problems in the early productions runs, in 1974, after some 2¼ thousand Bugs had been built, the zany little machine was dropped; not even the oil crisis of the time (which had doomed a good number of bigger, thirstier cars) and the nasty recession which followed could save it.  Even in its best years it was never all that successful, essentially because it was really a novelty and there were “real” cars available for less money.  Still, the survivors have a following in their niche at the lower end of the collector market and it's a machine truly like no other.

The business of spying is said to be the “second oldest profession” and even if not literally true, few doubt the synergistic callings of espionage and war are among man’s earliest and most enduring endeavors.  Although the use of “bug” to mean “equip with a concealed microphone” seems not to have been in use until 1946, bugging devices probably go back thousands of years (in a low-tech sort of way) and those known to have been used in Tudor-era England (1485-1603) are representative of the way available stuff was adapted, the most popular being tubular structures which, if pressed against a thin wall (or preferably a door’s keyhole) enabled one to listen to what was being discussed in a closed room.  Bugging began to assume its modern form when messages began to be transmitted over copper wires which could stretch for thousands of miles and the early term for a “phone bug” was “phone tap”, based upon the idea of “tapping into” the line as one might a water pipe.  Bugs (the name picked-up because many of the early devices were small, black and “bug-like”), whether as concealed microphones or phone taps, swiftly became part of the espionage inventory in diplomacy, commerce and crime and as technology evolved, so did the bugging techniques.

Henry Cabot Lodge Jr (1902–1985), US Ambassador to the UN (United Nations) at a May 1960 session of the Security Council, using the Great Seal bug to illustrate the extent of Soviet bugging.  The context was a tu quoque squabble between the Cold War protagonists, following Soviet revelations about the flight-paths of the American's U2 spy planes.  Lodge would be Richard Nixon’s (1913-1994; US president 1969-1974) running mate in that year's presidential election.     

A classic bug of High Cold War was the Great Seal bug, (known to the security services as the thing), a Soviet designed and built concealed listening device which was so effective because it used passive transmission protocols for its audio signal, thereby rendering it invisible to conventional “bug-detection” techniques.  The bug was concealed inside large, carved wooden rendition of the US Great Seal which, in 1945, the Kremlin presented as a “gift of friendship” to the US Ambassador to the USSR Averell Harriman (1891-1986); in a nice touch, it was a group of Russian school children who handed over the carving.  Sitting in the ambassador’s Moscow office for some seven years, it was a masterpiece of its time because (1) being activated only when exposed to a low-energy radio signal which Soviet spies would transmit from outside, when subjected to a US “bug detection” it would appear to be a piece of wood and (2) as it needed no form of battery or other power supply (and indeed, no maintenance at all), its lifespan was indefinite.  Had it not by chance been discovered by a communications officer at the nearby British embassy who happened to be tuned to the same frequency while the Soviets were sending their signal, it may well have remained in place for decades.  Essentially, the principles of the Great Seal bug were those used in modern radio-frequency identification (RFID) systems.

Bob

Bob (pronounced bobb)

(1) A short, jerky motion.

(2) Quickly to move up and down.

(3) In Sterling and related currencies, a slang term for one shilling (10c); survived decimalisation in phrases like "two bob watch", still used by older generations).

(4) A type of short to medium length hairstyle.

(5) A docked horse’s tail.

(6) A dangling or terminal object, as the weight on a pendulum or a plumb line.

(7) A short, simple line in a verse or song, especially a short refrain or coda.

(8) In angling, a float for a fishing line.

(9) Slang term for a bobsled.

(10) A bunch, or wad, especially a small bouquet of flowers (Scottish).

(11) A polishing wheel of leather, felt, or the like.

(12) An affectionate diminutive of the name Robert.

(13) To curtsy.

(14) Any of various hesperiid butterflies.

(15) In computer graphics (using "Bob" as a contraction of Blitter object), a graphical element (GEL) used by the Amiga computer (the first consumer-level computer which handled multi-tasking convincingly).  Technically, Bobs were hardware-generated objects which could be moved on the screen by the blitter coprocessor.  Bobs were an object of some veneration among the demosceners (the computer art subculture that produces and watches demos (audio-visual computer programs)), Bobs rated according to their the volume and dynamics of movement.

(16) In Scotland, a bunch, cluster, or wad, especially a small bouquet of flowers.

(17) A walking beam (obsolete).

1350–1400: From the Middle English bobben (to strike in cruel jest, beat; fool, make a fool of, cheat, deceive), the meaning "move up and down with a short, jerking motion," perhaps imitative of the sound, the sense of mocking or deceiving perhaps connected to the Old French bober (mock, deride), which, again, may have an echoic origin. The sense "snatch with the mouth something hanging or floating," as in bobbing for apples (or cherries), is recorded by 1799 and the phrase “bob and weave” in boxing commentary is attested from 1928.  Bob seems first to have been used to describe the short hair-style in the 1680s, a borrowing probably of the use since the 1570s to refer to "a horse's tail cut short", that derived from the earlier bobbe (cluster (as of leaves)) dating from the mid fourteenth century and perhaps of Celtic origin and perhaps connected in some way with the baban (tassel, cluster) and the Gaelic babag.  Bob endures still in Scots English as a dialectical term for a small bunch of flowers.  Bob is a noun & verb, bobber & boggy are nouns, bobbing is a noun & verb, bobbed is a verb & adjective, bobbish is an adjective and bobbingly & bobbishly are adverbs; the noun plural is bobs.  When used as a proper noun, there's an initial capital.

Australian politician Bob Katter (b 1945) with cane toad.

An introduced pest (ie the cane toad), Mr Katter's idea is children should be given guns (air rifles) to hunt them, each carcass attracting a bounty of 40 cents ("four bob" in the old slang).  This photograph is thus potentially "a five bob".  Affectionately, Mr Katter is known as “his Bobness” and, depending on who is asked, is either (1) an intellectual or (2) barking mad.  Between 1974-1992, Mr Katter served in the Queensland state parliament but since 1993 has been the member for Kennedy (at 567,377 km² (219,066 sq miles) about the size of metropolitan France) in the Commonwealth House of Representatives.  Until 2001 he was a member of the National Party (the old Country Party), after which he sat as an independent.  The suggestion which circulated implying he was asked by the Nationals to vacate his seat after an IQ test revealed he was "too intelligent for the National Party" was fake news and wholly malicious.   

Two two bob coins: Obverse (heads, left) and reverse (tails, right) of two 1945 Australian florins, minted in the same year as Mr Katter.

The coin at the top is one which spent some time in circulation while the more lustrous example below is a UNC (uncirculated coin) which would likely have spent its entire existence in collections.  Numismatists (coin collectors) will pay a premium for a UNC, a 1945 UNC Australian florin typically trading at four times the price of a circulated coin in good condition.  Now nominally equivalent to 20 cents (although a florin’s purchasing power was greater), it was worth two shillings (thus “two bob” in slang).  The group of "bob words" in English is beyond obscure and mostly mysterious.  Most are surely colloquial in origin and probably at least vaguely imitative, but have long become entangled and merged in form and sense (bobby pin, bobby sox, bobsled, bobcat etc).  As a noun, it has been used over the centuries in various senses connected by the notion of "round, hanging mass" and of weights at the end of a fishing line (1610s), pendulum (1752) or plumb-line (1832).  As a description of the hair style, although dating from the 1680s, it entered popular use only in the 1920s when use spiked.  As a slang word for “shilling” (the modern 10c coin), it’s recorded from 1789 but no connection has ever been found and the origin of this is unknown.  In certain countries, among older generations, the term in this sense endures in phrases like “two bob watch” to suggest something of low quality and dubious reliability.

UK Prime Minister Lord Salisbury (Robert Arthur Talbot Gascoyne-Cecil, 1830–1903; UK Prime Minister for thirteen years variously 1885-1902.

The third marquess was, in the words of of Winston Churchill (1875-1965; UK prime-minister 1940-1945 & 1951-1955): "prime-minister since God knows when" and the affectionate diminutive of his grandson (Robert Arthur James Gascoyne-Cecil 1893-1972; Fifth Marquess of Salisbury 1947-1972) was "Bobbety".  The phrase "Bob's your uncle" is said often to have its origin in the nepotism allegedly extended by Lord Salisbury to his favorite nephew Arthur Balfour (1848–1930; UK Prime Minister 1902-1905), unexpectedly promoted to a number of big jobs during the 1880s.  The story has never convinced etymologists but it certainly impressed the Greeks who made up a big part of Australia's post-war immigration programme, "Spiro is your uncle" in those years often heard in Sydney and Melbourne to denote nepotism among their communities there.

The other potential source is the Scottish music hall, the first known instance in in a Dundee newspaper in 1924 reviewing a musical revue called Bob's Your Uncle.  The phrase however wasn't noted as part of the vernacular until 1937, six years after the release of the song written by JP Long, "Follow your uncle Bob" which alluded to the nepotistic in the lyrics:

Bob's your uncle
Follow your Uncle Bob
He knows what to do
He'll look after you

Partridge's Dictionary of Slang and Unconventional English (1937) notes the phrase but dates it to the 1890s though without attribution and it attained no currency in print until the post-war years.  Although it's impossible to be definitive, the musical connection does seem more convincing, the connection with Lord Salisbury probably retrospective.  It could however have even earlier origins, an old use noted in the Canting Dictionary (1725) in an entry reporting "Bob ... signifies Safety, ... as, It's all Bob, ie All is safe, the Bet is secured."

Of hair

A bob cut or bob is a short to shoulder-length haircut for women.  Historically, in the west, it’s regarded as a twentieth-century style although evidence of it exists in the art of antiquity and even some prehistoric cave-paintings hint it may go way back, hardly surprising given the functionality.  In 1922, The Times (of London), never much in favor of anything new, ran a piece by its fashion editor predicting the demise of the fad, suggesting it was already passé (fashion editors adore the word passé) although the photographic record for the rest of the decade does suggest it took the bright young things of the age a while to take the paper's hint.  Certainly, bobs were less popular by the difficult 1930s but in the 1960s, a variety of social and economic forces saw a resurgence which has never faded and the twenty-first century association with the Karen hasn't lessened demand (although the A-line variant, now known in the industry as the "speak to the manager" seems now avoided by all except those for whom there are few viable alternatives).  The connection with the Karen is the second time the bob has assumed some socio-political meaning; when flaunted by the proto-feminists of the 1920s, it was regarded as a sign of radicalism.  The popularity in the 1920s affected the millinery trades too as it was the small cloche which fitted tightly on the bobbed head which became the hat of choice.  Manufacturer of milliner's materials, hair-nets and hair-pins all suffered depressed demand, the fate too of the corset makers, victims of an earlier social change, a phenomenon which would in the post-war years devastate the industries supporting the production of hats for men.  In the 1970s, some optimists (some of whom may have been men), noting one well-publicized (though not widely practiced) aspect of second-wave feminism, predicted the demise of the bra but that garment endured and flourishes to this day.

Variations on a theme of bob, Marama Corlett (b 1984. left) and Lindsay Lohan (b 1986, right), Sick Note, June 2017.

Hairdressers have number of terms for the variations.  The motifs can in some cases be mixed and even within styles, lengths can vary, a classic short bob stopping somewhere between the tips of the ears and well above the shoulders, a long bob extending from there to just above the shoulders; although the term is often used, the concept of the medium bob really makes no sense and there are just fractional variations of short and long, everything happening at the margins.  So, a bob starts with the fringe and ends being cut in a straight line; length can vary but the industry considers shoulder-length a separate style and the point at which bobs stop and something else begins. Descriptions like curly and ringlet bobs refer more to the hair than the style but do hint at one caveat, not all styles suit all hair types, a caution which extends also to face shapes.

Greta Thunberg: BB (before-bob) and AB (after-bob).

The style received an unexpected imprimatur when Greta Thunberg (b 2003) opted for a bob (one straddling chin & shoulder-length).  Having gained fame as a weather forecaster, the switch to shorter hair appears to have coincided with her branching out from environmental activism to political direct action in the Middle East.  While there's no doubt she means well, it’s something that will end badly because while the matter of greenhouse gasses in the atmospheric can (over centuries) be fixed, some problems are insoluble and the road to the Middle East is paved six-feet deep with good intentions.  Ms Thunberg seems not to have discussed why she got a bob (and how she made her daily choice of "one braid or two" also remained mysterious) but her braids were very long and she may have thought them excessive and contributing to climate change.  While the effect individually would be slight, over the entire population there would be environmental benefits if all those with long hair got a bob because: (1) use of shampoo & conditioner would be lowered (reduced production of chemicals & plastics), (2) a reduction in water use (washing the hair and rinsing out all that product uses much), (3) reduced electricity use (hair dryers, styling wands & straighteners would be employed for a shorter duration) and (4) carbon emissions would drop because fewer containers of shampoo & conditioner would be shipped or otherwise transported.

Sydney Sweeney (b 1997) with new bob, Variety's Power of Women 2025 Event, Beverly Hills Hotel in Los Angeles, California, October 2025.

Actor Sydney Sweeney (b 1997) seemed not to have revealed whether it was Greta Thunberg who inspired her to get a bob but the symmetrical cut made quite a splash when she appeared on the red carpet at Variety's Power of Women 2025 Event.  The reaction universally was favourable but also noted by critics was her sparkling silver full-length gown from the spring 2026 collection of Christian Cowan (b 1995) & Elias Matso (b 2002); it’s fair to say dress overshadowed hair, fetching though the latter was.  The gown was called “Twisted Crystal Mesh Tee” and for deconstructionist fashionistas, the piece was a delight of detail in sheer fabric including bell sleeves, a scooped neckline, a form-fitting bodice with an intricately crafted twisted waist, lending a cinched effect which merged effortlessly to a lace-up fastener at the back, constructed with a corset-tie motif: coming or going, she looked good.  So lovely is Sydney Sweeney she would look good in just about anything but she certainly knows how to get the most from a garment, her underwear limited to “nude knickers” with diamond drop earrings and rings from EFFY.

Her appearance in that dress of course provoked the digital traffic she would have expected and it’s hard to disagree with the feminist critics who suggested the juxtaposition of well-filled gown with the speech she delivered at the event was a device intended deliberately to illustrate the behavioral phenomenon she’d discussed in earlier interviews: That women can be defined as sexy or serious but not both simultaneously.  As evidence of that, the extent of the on-line coverage of how Ms Sweeney looked in the dress may be compared with the minimal attention afforded the speech she delivered from the podium, the former already joining the Alexandre Vauthier (b 1971) LRD (little red dress) worn by & Bella Hadid (b 1996) Cannes Film Festival in May 2016 as one of the dresses of the twenty-first century.  Of her words, most of the “cultural commentators” seemed intent on criticizing what they deemed the apparent discontinuity between her wishing to be taken seriously while looking so stunningly sexy, apparently missing the point that in bundling her body, the garment in which it was wrapped and the text she delivered as a single installation, she made her point well, dress and body just part of her text.

Ever since the Canadian theorist Marshall McLuhan (1911–1980) explained the concept in Understanding Media: The Extensions of Man (1964), it’s been understood “the medium is the message”, his theory being it is the channel or technology through which information is transmitted which matters more than the content in the shaping human experience and society.  While that obviously wasn’t an absolute rule, the notion was helpful, decades before TikTok, in providing a model of the way a structure can have social effects independent of its content.  To define “medium”, McLuhan cast a wide net, including not only the then familiar (and dominant) television & print, but any channel through which information passes, including speech, gesture and appearance.  The person delivering a message is thus a medium and the reaction of an audience to the words of a glamorous, attractive woman can be very different to that extended to someone plain, even if both recite the same text with the same tonal technique.

So, Ms Sweeney’s dress wasn’t just packaging, it was part of the meaning and that was not what she implied but what the audience inferred; what “the medium is the message” meant was the form of delivery and the embodied qualities of the communicator are inseparable from the content’s impact.  This was heady stuff in 1964 and, thirty-odd years on, the internet would gain critical mass and, at scale, prove his principle but his idea wasn’t new, the line of thought running through Western philosophy from Aristotle (384-322 BC) who called it “ethos” to Leo Strauss (1899–1973) who wrote of a kind of “authenticity”.  Unfortunately, Strauss was disturbed by way the writings of Friedrich Nietzsche (1844–1900) were so accessible they were there for Nazis and others to make of them something else so his meaning(s) existed in a kind of elaborated code it took some time to learn but definitely he was in the Aristotelian tradition McLuhan would have understood.  It’s a long way from Nietzsche to Sweeney but from her back to McLuhan, it’s not that far.

Bob identification: By their bob they shall be known

Asymmetrical Bob: Another general term which describes a bob cut with different lengths left and right; they can look good but should not be applied to all styles.  The effect is often most dramatic when combined with some variant of the Shaggy (JBF).

A-line bob: A classic bob which uses slightly longer strands in front, framing the face and, usually, curling under the chin; stylists caution this doesn’t suit all face shapes.

Buzz-cut bob: Known also as the undercut (pixie) bob, and often seen as an asymmetric, this is kind of an extreme inverted mullet; the the usual length(s) in the front and close-cropped at the back.  It can be a dramatic look but really doesn’t suit those above a certain BMI or age (although the former seem often unable to resist the look).

Chin-length bob: Cut straight to the chin, with or without bangs but, if the latter is chosen, it’s higher maintenance, needing more frequent trims to retain the sharpness on which it depends.  Depending on the face shape, it works best with or without fringe.

Inverted bob: A variation on the A-line which uses graduated layers at the back, the perimeter curved rather than cut straight. Known also as the graduated bob, to look best, the number of layers chosen should be dictated by the thickness of growth.

Shaggy bob: A deliberately messy bob of any style, neatness depreciated with strategic cutting either with scissors or razor, a styling trick best done by experts otherwise it can look merely un-kept.  The un-kept thing can be a thing if that’s what one wants but, like dying with gray or silver, it's really suitable only for the very young.  Some call this the choppy and it’s known in the vernacular of hairdressing as the JBF (just been fucked).

Spiky bob: This differs from a JBF in that it’s more obviously stylised.  It can differ in extent but with some types of hair is very high maintenance, demanding daily application of product to retain the directions in which the strands have to travel.  Not all hair is suited to the look and while product can compensate for much, beyond a certain point, there is a law of diminishing returns. 

Shingle bob: A cut tapered very short in the back, exposing the hairline at the neck with the sides shaped into a single curl, the tip of which sits at a chosen point on each cheek.  This needs to be perfectly symmetrical or it looks like a mistake.

Shoulder-length bob: A blunt bob that reaches the shoulders and has very few layers; with some hair it can even be done with all strands the same length.  Inherently, this is symmetrical and a remarkably different effect is created depending on whether it's done with or without a fringe although hairdressers caution this is not a style best suited to "round" faces and with those it can be necessary to experiment, a fringe sometimes improving things, sometimes not.

Speak to the manager bob: Not wishing to lose those customers actually named Karen, the industry shorthand for the edgy (and stereotypically in some strain of blonde) bob didn’t become “Karen”.  The classic SttM is an asymmetric blonde variation of the A-line with a long, side-swept fringe contrasted with a short, spiky cut at the back and emblematic of the style are the “tiger stripes”, created by the chunky unblended highlights.  It's now unfashionable though still seen because it remains the "go to cut" for women of a certain age who have been persuaded the style they've stuck to since they were 19 is no longer flattering.
